Designed for efficient seedbed preparation

The NZ Aggressive cultivator is designed for efficient seedbed preparation, the many working steps of the cultivator reduce the number of passes needed for seedbed preparation.

The machine is capable of transforming the most cloddy and uneven surface into a perfect environment for seed to germinate.

NZA seedbed cultivators offer superior performance to farmers who demand the very best.

Equipment for many different conditions

All NZA are equipped with front Crossboard including a stabiliser bar. In conditions where a more thorough levelling is required, a Crossboard could also be put in the rear of the machine.

NZA has a heavy duty frame construction equipped with strong Agrilla Cobra tines, which are distributed over 5 or 6 rows with 7.5 cm tine spacing. The space between each row is approximately 50 cm and the space between each tine in a row is about 38 cm. This combination optimizes both soil throughflow capacity and seedbed quality.

If a roller is coupled behind the NZA, the total number of passes required is reduced and better tillage and consolidation is obtained with less passes.

Depth setting from cabin

The depth can be set on the move via the cabin. The depth can be adjusted depending on different conditions in the field enabling an optimum seedbed preparation.

Boggie wheels

NZA is equipped with large boggie wheels to keep the machine smooth and level during operation even if the ground is uneven. The different wheel pairs are separated lengthwise in order to further stabilise the machine.

Working widths

NZA is available from 5 m up to 10 m working width. The 7 m and 9 m models can easily be extended to 8 and 10 m respectively.

Tested in very tough conditions

NZA has a high quality design and has been tested in the toughest conditions possible. Frame, tines, wheels and hydraulics have proven reliability with years of experience built in.

NZ Aggressive with Control function

Master and slave system

1. Powerful CrossBoard levelling board

The front CrossBoard levels and crushes plough furrows and shifts large amounts of soil. The CrossBoard is supplied with stabilizer bars, which connect all CrossBoard tines together so that they help each other. This makes the CrossBoard even more powerful in order to reduce clods and make the soil more even.

2. AgrillaCobra tines

The upright AgrillaCobra tines are designed to maximise the movement of soil. The strong and durable tines work the soil to produce an excellent seedbed.

The tine depth can be adjusted during operation from the cabin. The clearance under the frame and the distribution of tines over 5 or 6 axles gives a good flow of soil through the machine. The distance between tines is 7.5cm which distributes the soil so that larger clods are placed on the top and smaller particles deeper, which is favorable for early drilling. If goosefoot points are used weed roots could efficiently be cut off. The weight from the NZ Aggressive presses the tine straight from above. The point is positioned slightly behind the tine attachment whereby sideways vibrations are achieved, improving soil throughflow and work quality.

3. Rear CrossBoard levelling

The optional rear CrossBoard including a stabilising bar finishes the levelling work done by the NZ Aggressive and is controlled with a parallel transfer linkage from the front CrossBoard. With this option the cultivator contributes to even better depth precision and levelling.

4. Following harrow

The following harrow loosens and creates an evaporation protection layer. It also protects the surface from crusting after heavy rains. The following harrow further improves the sorting of bigger aggregates on the surface and smaller particles deeper.

Standard Features

Generous stone trays

Two large stone trays enable the collection of stones to leave a perfect seedbed.

CrossBoard

CrossBoard consists of hardened CrossBoard tines with angled wearing plates to provide aggressive cultivation. Clods are crushed and the soil is levelled. The CrossBoard is equipped with a stabiliser bar for increased levelling capacity. The aggressiveness is easily controlled from the cab. There are various wearing plates available as option.

AgrillaCobra tines

The point of the AgrillaCobra is placed relatively far back improving the flex both backwards and upwards. This affects stone handling and lifetime very positively. The upright AgrillaCobra tines are designed to maximise the movement of soil for optimised work result. The tine is manufactured from special hardened steel in dimensions 10x45 mm, which make the AgrillaCobra tine strong and very durable, and give it a unique depth holding ability. The Agrilla standard points are turnable and ensure low running costs.

Depth setting from cabin

The tine depth can be adjusted during operation from the cabin with the aid of a memory hydraulic cylinder.

Strong proven frame

NZ Aggressive is equipped with a heavy duty quality frame with 60x60 mm tubes which ensures a very long lifetime.

Maintenance-free ball bearings

The angular contact ball bearing units efficiently absorb any disruptive lateral forces that may arise. The bearings are maintenance-free and normally require no after-adjustment.

Smart boggie

NZA has boggie wheels where 40% of the weight is carried by the front wheel and 60% of the weight is carried by the rear wheel for improved contour following. This minimises the risk of soil bulldozing in front of the wheels.

Stable boggie placement

The wing boggie wheels are placed in front of the centre boggie wheels. This gives the machine a better stability and depth precision lengthwise.

Broad wheel base

NZ Aggressive has up to 8 wheels for optimal depth keeping. The broad wheel base keeps the machine afloat also on soft soils. This enables early seedbed preparation and drilling, saving optimal amount of humidity for the seed. Wheel scrapers keep the tyres clean from sticky soils.

Point options

Agrilla point 15 mm

The turnable Agrilla point is a thick point for tough conditions, long lifetime and good depth keeping. 15 mm wide and 15 mm thick.

Marathon point 18 mm

For extra long lifetime and less downtime Väderstad offers the Marathon point series, 18 mm.

Marathon point 25 mm

For extra-long lifetime and less downtime Väderstad offer the Marathon point, 25 mm.

Super point 350mm

The turnable 35 mm Super point is standard.

Goosefoot point

The 135 mm goosefoot point gives a full cut out and makes NZ Aggressive a true weed killer. This is particularly useful in organic farming.

Options

The track eradicators loosen up the wheel tracks of the tractor effectively and can be adjusted individually to the desired depth.

SingleKnife

The CrossBoard can be equipped with single or double knives. The SingleKnife will cut clods in the top soil in order to reduce clod sizes. Fastened with the Väderstad QuickChange System - no tools needed.

DoubleKnife

The CrossBoard can be equipped with single or double knives. The DoubleKnife is a good way to break a crust that prevents the plants from emerging. Fastened with the Väderstad QuickChange System - no tools needed.

Wing extensions

The 7 m and 9 m models can easily be extended to 8 and 10 m respectively. This improves the capacity at a low cost.

Rear CrossBoard

The rear CrossBoard with a stabilising bar levels efficiently. It moves parallel to the front CrossBoard but is less aggressive. The angle can be set independently from the angle of the front CrossBoard. It is useful where a particularly fine seedbed is required or on heavy soil types.

Following harrow

The following harrow levels and stratifies the soil after the tines. Both angle and pressure can easily be adjusted. If reversing with the following harrow in the ground it automatically flips back to prevent damage.

Connecting drawbar

A connecting drawbar with hydraulic couplings makes it possible to attach a roller behind the cultivator to further reduce the amount of passes.

6th row of tines

A 6th row of tines gives a larger spacing between the tines, which improves throughflow and residues handling.

LED lights

A high-quality lighting kit is available as an option and can easily be retro-fitted on existing machines. LED-type lights are used, for long life in demanding environments.
